Interference Power displays the real-time interference strength of channels. On Interference Power, the horizontal coordinate indicates channels, and the vertical coordinate indicates the interference signal strength. Interference types are distinguished by the color.

Given that the amplitude spectrum and the phase spectrum, taken together, uniquely describe the time signature of a signal, it is pertinent to ask how these spectra, taken separately, contribute to the signal. As a general rule of thumb, the phase spectrum is more important than the amplitude...
单音的情况下CW,Video Signal 都是DC成分,所以Video Bandwidth并不会影响输出结果,但Two Tone讯号如同前面的提到的脉冲讯号,如果视频频宽VBW设定很小的时候,扫描时间够久就会剩变成一个没有变化的直流讯号,看不到双音讯号的调变行为,这直流读值也就是平均电压或平均功率Average Power。
ELLIOTT, in Handbook of Digital Signal Processing, 1987 E Two-Dimensional DTFT Let an image x(r, s) be sampled at intervals of T1 and T2 along the r and s axes, respectively, yielding the 2-D sequence x(m, n). The spectrum will be 2-D with periods 1/T1 and 1/T2 along the ...
Through time accumulation and image stacking, the energy changes of the signal can be easily displayed. The built-in sequence function allows customers to create and execute the required test steps directly on the instrument without the need of a PC connection. The GSP-8000 series is a basic ...

to a radio station and the announcer says, "You are listening to 91.5 FM WRKX The Rock!," what the announcer means is that you are listening to a radio station broadcasting a frequency modulated (FM) radio signal at a frequency of 91.5 megahertz, with FCC-assigned call letters of WRKX...
